Publicly traded cybersecurity companies have become popular in light of complex cyber attacks, an increasingly remote workforce and the growing number of online connections.

Top Public Cybersecurity Companies

  • Palo Alto Networks

  • Check Point Software Technologies

  • A10 Networks
  • F5
  • Varonis

Within this interconnected ecosystem, the costs of cybercrimes could soar to as much as $10.5 trillion per year by 2025. Businesses have responded by investing in cybersecurity measures, keeping the global cybersecurity market on pace to reach $657 billion by 2030. Cybersecurity is thriving on this concentration of capital, and public cybersecurity companies provide a way in for the average investor. 

In contrast to private companies, publicly traded cybersecurity companies allow anyone to own shares in the company and earn some of the profits. And because they can more easily access funds from larger investor pools, these businesses must abide by strict SEC regulations. This way, public companies can quickly fund new projects and growth initiatives while maintaining trust with investors and financial authorities. 

Fast funding will be necessary to keep up with the field, which has already incorporated technologies like artificial intelligence and machine learning to accelerate processes. Investors may then want to gain an early foothold in the industry before it takes off in the coming years.   

With that in mind, we’ve gathered 18 publicly traded cybersecurity companies you should know about.
